Frequently Asked Questions
Q: What does the NF 005535 split lock washer do?
A: The NF 005535 is a 5/16 inch zinc-plated split lock washer that prevents bolts and fasteners from loosening due to vibration. The split design creates spring tension under the bolt head.
Q: What is the diameter and hole size of the NF 005535 washer?
A: The NF 005535 is sized for 5/16 inch diameter bolts and fasteners. It has an inner hole diameter of 5/16 inch and an outer diameter suitable for spreading load on gravity conveyor components.
Q: Is the NF 005535 suitable for outdoor or wet environments?
A: The zinc-plated (ZP) finish provides corrosion resistance for general industrial environments and mild moisture exposure. For high-moisture, food-grade, or chemical environments, verify that the zinc coating is adequate for your specific facility conditions.
Q: How should split lock washers like the NF 005535 be used?
A: Split lock washers are placed on the bolt shaft before the nut to maintain fastener tightness. They are commonly used on gravity conveyor frames, brackets, and modular connections subject to vibration and shock loads.
Q: When should the NF 005535 washers be replaced?
A: Replace split lock washers if they become flattened, corroded, or if the bolts they secure show signs of loosening. Washers that have lost their spring tension should be replaced during routine conveyor maintenance.
